ful Improvements in Connectors for Electric Conductors, of which the following .is a specification.

This invention relates to devices for connecting electric, conductors, and has for its object the provision of a device of this character in which an etlicient joint can be made between electric conductors andwhich is -eX- tremely simple and durable. Y

One of the objects of my invention is to provide a connector having a body portion which may be molded in one piece.

In carrying out my -invention the terminals are mounted in a hollow casing which is molded. In order to enable the casing to be readily molded the wall between the terminals is made separable and this wall is held in place by means of a pin or the like which holds the terminals in position. I likewise provide improved terminals which are Vso constructed as to make an eilicient joint, the spring-pressed portion moving parallel to itself so that a uniform bearin y is obtained. Other features of novelty wil likewise appear in the course of the following specilication, in which I have shown my invention embodied in `concrete form for purposes of illustration.

Referring to the drawing, Figure 1 is a longitudinal View of my connector plug; Fig. 2 is Aacrosssection of the same taken -on the line 2-2 of Fig. 1; Fig. 3 is an end view lof the plug; Fig. 4 is a View of the opposite end; Fig. 5 shows the terminals int-wo views, and Fig. 6 shows the separating wall beitween the terminals likewise in two views. y

Referring to the drawing, 10 is a casing for the connector plug made of elongated oval shape, as shown. This plug is made soA as to taper toward both ends, the taper being greatest toward its rearend. This plug is` preferably made by molding it into shape. The particular material used forms no part of my invention. 4I have found, however, that the steam-hardened compound described and claimed in an application filed by Mr. L. E. Barringer, Serial No. 274,409, serves the purpose very well since it is extremely tough, hard and easily produced. This casing is molded hollow as shown, the shape of sidesioa'dmit the separating wall 12. The

casing at oneend is provi d with screw 4threads 13 to receive a bushing 14, and at 'the opposite endis-shaped, as shown in Fig.- 4, to receive terminals of the well-known type. The1 casing is likewise aperturedon opposite sides at 15 to receive the pins 16 of the terminals.

The separating wall 'l2 is'formed as shown in Figs. 3, 4 and, and is arranged centrally of the plug being held in place by means of a pin 18.

The terminals are made as shown in Figf 5 consisting 'of metallic plates 19 and 2O which are grooved so that when placed to- I A'geth'er the adjacent grooves form a socket 21.

The plate 19'is longer than the plate 20 and a thlrd plate 22 is secured to the elongation being held in place by the pinl. A threaded opening is formed between the plates 19 and 22 to receive a perforated screw 23 into which the wire fits. 4A 'spring 24, one end of which is held in place under the shoulder of pin 16, has its free end rpressing against themovable plate 20, the spring entering into the plateat., slots 25 so as to prevent lateral displace'ment of the plate. By this "constrnctionea, uniform bearing is obtained? since the plate20 moves substantially parallel withtself. A'spring 26 is arranged over the'conductors 27 "and is mount'- ed on the bushing v14. Y'This spri prevents the 'wires Afrom being sharplyrexed and therelay..i eventually broken. Q

In assembling this plug the conductors 27 are" passed through the bushing 14 and" thence through the entire casing. The wires are then secured in place-by the terminals by passing them through the perforated screws 23 which are then screwed down so as to fasten the wire. The terminals are then drawn back into the casing until the pins'l enter the ,apertures 15. The insulatin wall 12 is then inserted between the termina s and the pin- 18 passes through the .wall to hold the parts together. Onescrew only is," therefore, required in assembling the parts.

It will thusbe'seen that I have provided a connector plug which may be readlly molded butwhich when assembled is of such'a shape that it separates the terminals and holds 4them in place in a very etlicient manner.

While I have describe-d my invention as embodying certain features of,v construction and arrangement'of parts, it should `be understood that I do not limit my invention in 'these particulars except-in so far as it is limitedby the yscope of -the claims annexed hereto.

What I claim Vas new and desire to secure by Letters Patent of the United States, is

1. A connector for electric conductors comv -prising an insulating receptacle, a separable insulating element extending longitudinally thereof to form compartments, metallic ter,- minals Within the compartments locked in plac'e by said element, and means for holding the element in place. 2.- A connector for 'electric conductors comprising an insulating receptacle, a separable insulating element extending longitudinally thereof to form compartments, metallic terlminals Within the compartments locked in place by said element, and a pin passing through the receptacle and said element to .ble insulating element extending centrally thereof to form compartments, a metallic terminal having a pro]ect1on cntermg the Wall of the receptacle and locked 1n each 'compartment by said element, and means for securing the element in place.

5. A connector plug for electric conductors comprising an insulating receptacle having an opening therethrough, a-separable insulating element extending centrally of said opening and partiallyclosing one end of thereceptacle leaving two openings therethrough, and metallic terminals within the receptacle one on each side of said element in line with said openings'.

6. A connector for electric conductors com 'prising an insulating receptacle, a separable insulatingelement extending centrally thereof to form compartments, a metallic terminal locked in each compartment by said element, said terminal having a rojection entering the Wall of the receptac e, and means for securin the element in place.

7. Aconnector or electric conductors comprising an insulating receptacle, .a separa- A ble insulating element extending centrally thereof to form compartments, a metallic terminal locked in each compartment by said element, said terminal having a pivotal bearing on thev Wall of the receptacle, and means for securing the element in place.

. 8. A connector for electric conductors comp'rising an insulating receptacle, a separable insulatingv element extending centrally thereof to form compartments, a metallic terminal pivoted in each compartment and locked therein by said element, said terminal comprising cooperating. members having a relative movement in a plane at right angles to the plane in which the terminal moves on its pivot. 9. A socket terminal for electric conductors .comprising independent elongated strips correspondingly grooved and a spring arranged to engage one strip at one end only and press said strips together.

10. A socket terminal for electric conductors comprising a pair of independent elongated strips correspondingly grooved, and a spring secured to one of said strips and en'- gaging the other at one end only to press them together.

In witness whereof, I have hereunto set my hand this 27th day of March, 1908.
